Kant does receive considerable credit for his early conjectures. Gingerich is not shy in quoting him, nor many other authors, though the reference to him seems more respectful of his seed sowing, as valid and sound logic that preceeded his conclusions does not exist.

Copernicus dug back into the Greek past and found other seeds to help support ideas he had. These early Greeks were stated in his Revolutions to help bolster his heliocentric theory. However, his strength was in his evidence (eg Venus variability)
